Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed September 1, 1914. Serial No. 859,634.

' To all whom it may concern teners; and I do hereby declare thefollow-.

ing to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to fastening devices for securing extension boxeson the tops of wagon bodies; and it consists in the novel constructionand combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is an end View of a wagon body provided with atop box and fasteners according to this invention. Fig. 2 is a side viewof one of the fastening devices on one side of the wagon. Fig. 3 is across-section, taken on the line w-m in Fig. 2.

The wagon body 2 is of any approved construction, and 18 is an ordinarytop box which is placed on top of the wagon body temporarily for thepurpose of increasing its capacity.

In order to secure the top box in place fastening devices are provided,and each fastening device has two hooks 3 which are hooked over the topedges of the top box. Each hook has a long shank I formed of a flat barwhich bears against the side of the top box, and which has a laterallyprojecting rib or flange 5. This rib or flange has holes 6 arranged atshort distances apart. The hook and its shank may be formed of castmalleable iron, or they may be forged from a piece of angle-iron. Acrossbar 7 is arranged under the wagon body and has slots 8 formed inits end por- Gopies of this patent may be obtained for five cents each,by addressing the tions which project from under the wagon body. Rods 10are provided and have hooks 12 at their upper ends for engaging with anyof the holes 6. The lower end portions 14 of the rods are screwthreaded,and are provided with hand-nuts or thumbnuts 15. The rods are slippedinto the slots or openings 8, the hooks 12 being slipped into differentholes 6 according to the height of the top box to be secured. The lowersides 16 of the end portions of the crossbar are beveled a little wherethe nuts bear against them, so that the nuts cannot slip laterally whenscrewed up to fasten the top box in place.

Fastening devices constructed in this manner are very simple andinexpensive, and they permit the top box to be removed and replaced asoften as necessary, and with great facility.

What I claim is:

The combination, with a wagon body, and a top box; of hooks which engagewith the top edge of the top box and which have shanks formed of flatbars arranged to bear on the sides of the top box and which are providedwith laterally projecting ribs, said ribs each having a series of holesarranged one above another, a crossbar arranged under, the wagon bodyand having openings in its end portions, rods having hooks for engagingwith the holes in the lateral ribs and having screwthreaded end portionswhich project through the openings of the crossbar, and fastening nutsscrewed on the rods under the crossbar.

In testimony whereof I have afiixed my signature in the presence of twowitnesses.
